I need some help here. I've worked hard on my loads and am getting close with several rifle/bullet/powder combinations. My problem is that in several instances my groups spread out dead vertical. Left to right may vary by 1/4 to 1/2", but vertically the spread is more like an 1" to maybe 2".
One person told me that's evidence of uneven neck tension and/or crimping between one round and another. I have this problem with both bolt-action and AR rifles. Can someone give me an idea of what I'm doing wrong?
Thanks!
